A great way to bring Parents and Grandparents to Canada is through the Super Visa program. This program allows family members to come to Canada as long-term visitors on a multiple entry visa that may last up to 10 years. A Super Visa is valid for 2 years before it has to be renewed.
This is an ideal option for Canadian Citizens and Canadian Permanent Residents who are waiting to sponsor their parents for PR, or who currently do not qualify for Parental PR sponsorship.
The financial requirement for a Super Visa is less strict than PR sponsorship- the minimum necessary income (MNI) is 30% lower than that of PR sponsorship, and only 1 year of gross income must exceed the MNI vs 3 years with PR Sponsorship.
